Slotted Countersunk Flat Head Screw

The Slotted Countersunk Flat Head Machine Screw is a type of fastening hardware commonly used in mechanical and industrial applications. It features a flat head with a slotted drive, designed for use with a flathead screwdriver. The countersunk design allows the screw to sit flush or slightly below the surface of the material once installed, providing a smooth, streamlined finish. This screw is typically used in pre-threaded holes, offering a precise and secure fastening. It is widely used in industries like electronics, automotive, and machinery, where a neat and low-profile installation is required.
